To all whom z'tma y concmi:

'Be it knownthat I, ToNJns AUGUST CARL BOTH, a citizenofthe United States, and a accompany g drawings, which forma part This invention relates to electrical appa ratus and more particularly to socket shells and means for securing a cap and socket shell together; and'further relates to a de- 15 tachable chain guide, both as an article of manufacture and in combination with a shell and cap which hold it in its proper position.

'My'inventipn further relates" to certain details of construction which will be more pointed out in the claims.

fully described in the specification and In the accompanying drawings, showing illustrative embodiments of my invention and in which the same reference numerals refer to similar parts in the several figures,-Figure 1 is a side elevation of my M improved socket equipped withmy chain guide; Fig. 2 is a-horizontal section substantiallyonthe line 2-2 of Fig. 1; Fig. 3

is a horizontal section'of a modifiedform of shell, equipped with my attachable and detachable chain guide; Fig. .4 is a side elevation, partlybroken away, of one form of my improved chain guide; Fig. 5 is aside elevation of a shell. used with my chain guide which is shown in section; Fig. 6 is a side elevation of a socket shell equipped with a modified form of chain guide; Fig.7 is a horizontal section substantially on the line 7 7 of Fig. 6; Fig. 8 is a sectionalview on the line 8 8 of'F 1g. 7 looking in the direction of the arrows; Fig. 9is a plan viewof a cheek piece used. with this form of removable chain guide; Fig. 10 shows the guide and cheek piece about to be assembled, the cheek piece being shown insect-ion, and the guide in plan; Fig. 11 is' a longitudinal'section of a modified form of chain guide; Fig.

12 is a horizontal section showinga modified form of check piece; Fig. 13 is a perspective view of the cheek piece shown in Fig. 1.2

Fig. 14 is aside elevation, partly in section,

- showing my improved chain guide and chain guide or eyelet 3. This removable chain guide or eyelet 3 may begiven various forms and contours but is preferably formed from one piece of material and provided with spaced engaging members 4, 4, forming a groove 5, Fig. 2, within which removably fits the walls 6, 6 of the slot 2 of the shell 1, Fig. 5. This groove 5 of the removslant to the longitudinal axis of the chain guide 3, as shown in Figs. 1 and 2, though it 1 may be formed substantially at right angles to the longitudinal axis, as in Fig. 4. I

agonally on thechain guide so as to throw the interior end 7 of the chain guide 3 nearer the interior surface 8 of the shell 1 than would be the case if the groove 5 was formed at right angles to the longitudinal axisof the chain guide. With such a, diagonal whose end (not shown) is to pass through the interior bore of the chain guide. This type of socket is what isknown in the art as a pull socket. While I refer to my removable guide being a chain guide, it is, of course to be understood that I do not limit my invention to a guide for a chain for any suitable flexible operating member may be "used to operate the switch mechanism instead of the chain'and with which movable guide will cooperate.

After my improved chain guide 3, with the diagonal slot 5 is assembled by slipping the guide intof'the socket 2, so that the engaging members 4,'4 will lie on either side of the walls 6, 6 of the shell, the chain guide is held from vertical movement 'inthe slot .g z bgpmeansof the cap 8 which cooperates aqith guideand. the shell to hold the Fig. 5, for the reception of the removable,

able chain guide is preferably formed at a prefer, however, to form the groove 5-digroove the interior end 7 of the chain guide 1 3 will be located substantially tangentially to the member carrying the chain or other flexible operating member (not shown) my re chain guide immovable after it is once assembled.

I preferably secure the cap 8 to the shell 1 by means screws 9 extending longitudinally ot the shell 1 and passing through openin s 10 in the shell, their screw threaded ends cooperating with the screw threaded cars 11 immovably carried by the cap 8. The shell 1 is preferably cut away 10 at 12, 12 to receive these cars 11, 11 which in addition to the screws 9, 9 will prevent relative rotation of the cap and shell after they are once assembled.

ln some cases I may form a shell 13 with 15 an indented pocket l i, Fig. 3, one wall of which is slotted at 15 for the reception of the removable chain guide 16; the walls of the slot coi'ipei'atiny' with the groove 17 which preferably arranged in this con- 20 struction, at right angles to the longitudinal axis of the chain guide, Fig. 4.

in some cases It may reniovably secure the chain guide to the shell. by an additional element xvi 1h is orelei'ably stamped from sheet ll1( .i..il. This form. of my invention is shown in 6 to 10, inclusive, and Figs. .12 and 13. 'tead of forming the engag ing s1 laces l, l directly upon'the chain guide, I take an additional piece of material, preferably stamped metal, and "form a check piece l8, 9, provided with a central aperture 19 and with two lips 20, 20 which are bent down beneath the main portion of the check piece 18 so that they will en; upon. the interior surface 8 of Big. 7, while the main portion piccewvill be on the exterior of 7. in this term of my is secured to the by inserting its reduced porin the aperture 19 then knin'ling it so'that it will be'securely to the ch oh 7 'ied portion 28, Fig.7. shown in 1 5 the preferred 3. piece 30 provided with a body membei having an aperture 32 through which fits the r luced portion 33 of the horn '1 the same" being preferly the planeof the The horn 184 30 is any suitsstting the iat they of the shell, the exterior surface being en- 'a'ged by the tongues 37,. 3? on the body memoers.

In some cuses I provide a removable chain gui e 25, llig. 11, with grooves to Iceheld.

ec; by means of its shoulder.

Inovably engage the shell 1 and also provide it with a short inwardly extending throat 27, Fig. 11.

My removable chain guide is particularly advantageous when the electric light socket is to be mounted in and surrounded by a husk 28, Fig. 13. In such a construction after the cap 29 has been secured to th'e fixture 130, the terminals (not shown) carried by the socket body 131 areconnected to the feed wires and the chain orother flexible operating member 132 is passed out of the hole 133 in the husk 28. My removable chain guide 344s then threaded on the chain, or

Ether flexible operating member 32, and insorted through the hole or other opening 133 in the husk, bringing the slot 135 with in the husk and in position to cooperate with the walls 136, 136 of the slots 137 in the shell 38 which is then brought into operative position with relation to the cap 29" and scoured to it in any suitable manner such as by the longitudinally extending screws 9 when the removable chain guide will besecured from inoven'ient by the cap closing the upper portion or? the slot 137 in the shell. It will, therefore, be readily seen that my removable chain guide can be readily used with electric light sockets, even when theyare surrounded by an ornamental husk 28, and that my removable chain guide can be placed in position a fter the cap has been located in the husk and the socket wired. After usingmy removable chain guide with a husk, the socket can be readily disconnected from the husk by reversing the operation of assembling the parts above described, when the removable chain guide can be used on the same socket, or in another similar socket, if desired, the husk being either used or omitted.

In the preferred form of my invention I provide the shell 1 as well as 13 with an engaging arm or arms 40,40, Fig. 15 to cooperate with a slot or slots .41, 41 in the socket body 131 so that thesocket body will be properly positioned with relation to the longitudinal slot 2 in whichthe chain guide 3 is removably mounted. The engaging arm or arms 4.0 are preferably made by stampingthem out of the body of the shell as shown in Fi 15, though they, of course, may be'otherwise formed.

Having thus described this invention in 7 connection with several illustrative embodi- 1110 ments thereof to thedetailsrof which I donot desire to be limited, whatis claimed as new and what it isdesiied to secure by Let-' tors Patent is set forth in the appendedclaims. 125
